Tales of Vesperia / Graces TLZC compression

[oathkeeper9918]

so some guy reverse-engineered the TLZC compression format used in most of the Tales of games.

There's a python program at the bottom of the post, I couldn't get it to work though (I would get a 'list index out of range' error on line 37). Any way to convert it to a quickbms script?? Or if someone could get that python program to work, that's be great too!

sample TLZC-compressed files: http://www.mediafire.com/?6423f9rml64tsmd

What game is this?
I couldn't get it to work either.

Code: Select all

Traceback (most recent call last):
  File "decompress.py", line 39, in <module>
    decompress_tlzc(buf, open(sys.argv[2], "w"))
  File "decompress.py", line 31, in decompress_tlzc
    decompress_block(lzma_params, block, out, remaining)
  File "decompress.py", line 11, in decompress_block
    out.write(pylzma.decompress(block, size, maxlength=size))
TypeError: Error while decompressing: 6

You should send the samples to the author.

They're from Tales of Vesperia. But hey, you got farther than I did in executing it, at least.

I sent the samples to the author, not expecting to get too much though.

I made a quickbms script based on his post enjoy.

Code: Select all

idstring "TLZC"
get name basename
string name + ".FPS4"
comtype MSF
get version long
get tzsize long
get tsize long
goto 0x1D
set blockcount tsize
math blockcount += 0xFFFF
math blockcount /= 0x10000
for i = 0 < blockcount
get zsize short
putarray 0 i zsize
next i
for i = 0 < blockcount
savepos offset
getarray ZSIZE 0 i
if tsize >= 0x10000
append
clog MEMORY_FILE OFFSET ZSIZE 0x10000
append
else
append
if ZSIZE == 0
log MEMORY_FILE OFFSET tsize
else
clog MEMORY_FILE OFFSET ZSIZE tsize
endif
append
endif
math tsize -= 0x10000
math offset + ZSIZE
goto offset
next i
get SIZE asize MEMORY_FILE
log name 0 SIZE MEMORY_FILE

Doesn't work for the book_enemy files.

[chrrox]

those files are null?

[chrrox]

oops my bad
change the one line
i left a hard coded number in there from a file i tested.
updated post

Now it works for book_enemy_20, but still fails on the other non-null books_enemy's (eg: 18, 19).

It fails on the very last iteration of the loop.
Maybe you have to deal with the remaining block separately?

done

Thanks! The script works perfectly for Vesperia's and Graces' files

replace

Code: Select all

math blockcount + 0xFFFF
math blockcount / 0x10000

to

Code: Select all

math blockcount += 0xFFFF
math blockcount /= 0x10000

Thanks a lot.

Does this mean you can extract models from Tales of Graces F or Tales of Graces? I have some models from Vesperia Xbox but I want to know if you can get models from Vesperia PS3.
